Be it known that I, VILLIAM SCHOENBERG, a citizen of-the rgentine Republic, and residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller-Skates; and I do declare the following to be a full, clear, and exact description of the invention,

The foot plate, 18, is preferably This invention contemplates theconstruco the saine curvature and tion of a roller skate provided with ,meansfor transferring the alternately-appliedy pressure of the wearer into -rotary motion .adapted to carry said wearer over the ground.

The foot plate, 18, is over the ri ound bymeans of oblique stridesl further provided with a heel-engaging stop an my invention comprises the construction member, 25, formed with strap openings, 26. of a skate provided with a plurality of racl The rac bars, 16, arepositioned on oppobars engaging ratchet wheels iifridly mount site ends of the foot plate, 18, and the teeth of said bars preferably face rearwardly.

The wheels, 3 and 4, are and, consequent ,rotating the shafts, 1 and secured to the shafts, l and 2, by washers,

The shafts, 1 and 2, pand and the rack bars, 16, will ride freely connect with depending legs, 12 and 13, upward on the teeth of the ratchet wheels, which are positioned on o posite sides of 11, the pivotal connection of said bars perthe ratchet wheels, 11 and'frmed with ball niitting them to swing slightly outward earings for assuring a. free rotary movement of the shafts, 1

The plate, 14, is formed with openings,

2. A plurality of ,shafts provided with improved roller skate provides means whereby its wearer secuies a doubleA exercise in the manipulation of the skates over the ground, and that the rotation of said skate is increased, thereby enabling thewearer to travel more rapidly and with less effort.

4From the foregoing description, takenin connection with the accompanying drawing, the construction and operation of the invention will be readilyv understood without requiring a more extended explanation.

Various changes in the iorm, proportion and the minor details of construction may be resorted to without departing from the'principle or sacricing any o the advantages o the invention as defined in the appen e claims. Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is: y

i. A plurality ot shafts provided with wheels, ratchet wheels arranged on the shafts, a horizontally extending plate supported' on the shafts above the Wheels, a

the shafts intermediately of their ends, legs secured to the shaftsand extending above the same, a horizontally disposed plate arseries of guide pins secure to the compression plate and extending through opposite lpending lugs formed on the under side of the compression plate, rack bars adapted to slidably extend through the first mentioned plate and engage with the ratchet wheels depending lugs, said rack bars being formed at their upper ends with oii sets having the pockets adapted to bear against the under side of the compression plate for normally holding the rack bars in engagement with the ratchet' wheels, anda series of secured to the compression plate and adaptsprings arranged around the guide pins for ed to extend slidably. tlii'ough'the first inen-v under side of the compression plate adjacent tant from the horizontally disposed plate. to the rear and forward ends of said plate, rack bars adapted to impart motion to the ratchet wheels of the shafts and having nesses.
